Lifetime, harmonic distortion, insulation heating, power quality, reliability, insulation aging
An approach to estimate lifetime of power transformers, induction motors and cables at low power quality is proposed. The mechanism of decreasing the electrical equipment (EE) lifetime due to voltage distortion and unbalance is analyzed. Numerical examples illustrated the effect of voltage distortion, and unbalances on the EE lifetime span reduction are presented.
